Works about 50% of the time and seems to be more effective than the pills (I have tried 11 brands in pill form) and sprays. I have noticed that it is easy to lose the "window of opportunity" for actual sleep if I take it and decide to stay up a bit later to finish watching something on TV. It works but is very gentle and has never left me with a morning after feeling. I have chronic sleep problems and have found that it is best to switch out products because nothing seems to work for more than a week or two.

The effect can be subtle - it depends on how badly stressed you are and if that has thrown off your chemistry. It certainly never knocks me out but takes off the edge most of the time. This brand works well and I am on my 2nd bottle. I find it helps me sleep if I take it around 8 or 9 PM and then follow up with liquid melatonin around 10 PM.

These taste good - a little vitaminy but not too bad. I emailed Rainbow Light to double check on the "gelatin" listed in the product and they confirmed it is from a bovine source. Just be forewarned that they are not appropriate for vegetarians.

I really wanted to like these and they were fine in terms of taste. I felt no difference after 3 weeks of daily use so I will try a different type of B-12. I have had better luck with other B-12 supplements in the past.
